[0002] Currently used standard wire clamps are either semi-circular or full-circular. For customers who need to install the wire clamps themselves, installing semi-circular wire clamps is relatively cumbersome. Full-circular wire clamps are not very versatile; while they are easy to install, they may not achieve the required pull-out force after installation. Wire clamps that can meet the pull-out force requirements are time-consuming and laborious to install. Utility Model Content
[0003] In view of this, this application provides a self-locking wire clamping assembly with a simple structure that can achieve the required pulling force while also being easy to install.
[0004] According to one aspect of this application, a self-locking wire clamping assembly is provided for use in conjunction with a raised end cap structure, including a wire clamping buckle, a wire clamping block, and a protrusion. The wire clamping buckle is connected to the wire clamping block. The wire clamping buckle has a trapezoidal plate structure with an arc-shaped through hole extending through the top of the wire clamping buckle, forming a latch at both ends of the top of the wire clamping buckle, suitable for external wire harnesses to pass through the through hole. The wire clamping block has a rectangular plate structure with a U-shaped groove with openings at both ends on one side of the wire clamping block. Slots are formed at both ends of the U-shaped groove, and the slots cooperate with the latches, suitable for fixing external wire harnesses between the wire clamping buckle and the wire clamping block. The protrusion is disposed on the wire clamping block and located within the U-shaped groove.
[0005] In one possible implementation, a first groove is provided on one side of the pressure block. The first groove and the U-shaped groove are on the same side. The first groove is located at the bottom of the U-shaped groove, and the bottom of the U-shaped groove is connected to the top of the first groove.
[0006] In one possible implementation, the inner portion of the first groove near the bottom forms a slope with the plane of the first groove.
[0007] In one possible implementation, a positioning block is also included, wherein two positioning blocks are provided, respectively positioned diagonally above the two apex corners of the top of the first groove.
[0008] In one possible implementation, two second through holes are provided on the pressure block, and the pressure block is fixed to the external raised end cap structure by external bolts passing through the second through holes.
[0009] In one possible implementation, the distance between the two latches is the same as the distance between the two slots.
[0010] In one possible implementation, one side of the bump is a cylindrical structure, and the cross-section of the bump gradually decreases as it extends toward one side of the pressure block.
[0011] In one possible implementation, the number of bumps is multiple.
[0012] In one possible implementation, a plurality of the protrusions are arranged along the vertical direction of the pressure block.
[0013] In one possible implementation, a relief groove is provided on one side of the pressure block, the position of the relief groove corresponds to the position of the second through hole, and the number of relief grooves is two.
[0014] In one possible implementation, a relief groove is provided on one side of the pressure block, the position of the relief groove corresponds to the position of the second through hole, and the number of relief grooves is two.
[0015] The beneficial effects of this utility model are as follows: By setting a wire clamp, a wire clamp block, and a protrusion, the wire clamp is connected to the wire clamp block, and the wire clamp and the wire clamp block cooperate to fix the external wire harness. The wire clamp is a trapezoidal plate structure with an arc-shaped through hole on it, which passes through the top of the wire clamp. The external wire harness passes through the through hole, and this setting also allows the two ends of the top of the wire clamp to form a snap fastener. The wire clamp block is a rectangular plate structure with a U-shaped groove with openings at both ends on one side. The U-shaped groove is designed to match the through hole and form a space to accommodate the external wire harness. The two ends of the U-shaped groove have slots that cooperate with the snap fasteners. This setting can fix the external wire harness and is suitable for fixing the external wire harness between the wire clamp and the wire clamp block. The protrusion is set on the wire clamp block and located in the U-shaped groove.

[0023] like Figures 1 to 2As shown, this self-locking wire clamping assembly, used in conjunction with a raised end cap structure, includes a wire clamping buckle 100, a wire clamping block 200, and a protrusion 210. The wire clamping buckle 100 is connected to the wire clamping block 200. The wire clamping buckle 100 is a trapezoidal plate structure with an arc-shaped through hole that extends through the top of the wire clamping buckle 100, forming a latch 110 at both ends of the top of the wire clamping buckle 100, suitable for external wire harnesses to pass through the through hole. The wire clamping block 200 is a rectangular plate structure with a U-shaped groove with openings at both ends on one side. Slots 220 are formed at both ends of the U-shaped groove, which cooperate with the latches 110, suitable for fixing external wire harnesses between the wire clamping buckle 100 and the wire clamping block 200. The protrusion 210 is disposed on the wire clamping block 200 and located within the U-shaped groove.
[0024] Specifically, the self-locking wire clamping assembly includes a wire clamping clip 100, a wire clamping block 200, and a protrusion 210. The wire clamping clip 100 and the wire clamping block 200 are provided to fix the external wire harness. To increase the pulling force of the external wire harness, the protrusion 210 is also provided. The protrusion 210 is set on the wire clamping block 200 so that the protrusion 210 contacts the external wire harness, increasing the friction between the two, thereby increasing the pulling force of the external wire harness.
[0025] The specific structure of the 100mm wire clip is as follows: Figure 1 As shown, the wire clip 100 has a trapezoidal plate-like structure. An arc-shaped through hole is provided on the wire clip 100. This arc-shaped through hole not only penetrates the front and rear sides of the wire clip 100 but also the top of the wire clip 100. It should be noted that the front side of the wire clip 100 is as follows... Figure 1 As shown in the front, the back of the 100-type stitching buckle is as follows: Figure 1 The back side shown shows the top of the snap fastener 100. Figure 1 As shown above, the arc-shaped through hole penetrates the top of the wire clamp 100, forming two snap fasteners 110 on the top of the wire clamp 100. The snap fasteners are for engaging with the wire clamp block 200.
[0026] The specific structure of the wire clamping block 200 is as follows: Figure 2 As shown, the wire clamping block 200 has a rectangular plate-like structure. To provide space for fixing the external wire harness, a U-shaped groove is provided on one side of the wire clamping block 200, extending through the top of the wire clamping block 200. It should be noted that the top of the wire clamping block 200 is... Figure 2 As shown above, the bottom of the pressure block 200 is Figure 2 As shown below, in order to cooperate with the buckle 110, slots 220 are provided at both ends of the U-shaped groove. It should be noted that the two ends of the U-shaped groove are as follows: Figure 2As shown on the left and right sides, the buckle 110 and the slot 220 cooperate with each other, so that the wire clamp 100 is vertically clamped on the wire clamp block 200. At the same time, a space is formed between the arc-shaped through hole and the U-shaped groove, through which the external wire harness passes.
[0027] In order to increase the pulling force of the external wire harness, a protrusion 210 is also provided. The protrusion 210 is set on the U-shaped groove. This setting is to make contact with the external wire harness, thereby increasing the pulling force of the external wire harness.
[0028] In one possible implementation, a first groove is formed on one side of the pressure block 200. The first groove and the U-shaped groove are formed on the same side. The first groove is formed at the bottom of the U-shaped groove, and the bottom of the U-shaped groove is connected to the top of the first groove. The inner portion of the first groove near the bottom forms a slope with the plane of the first groove.
[0029] Specifically, such as Figure 2 As shown, in order to prevent the external wire harness from bending after fixing, a first groove is provided on one side of the wire clamping block 200. The first groove and the U-shaped groove are on the same side. The first groove is located at the bottom of the U-shaped groove, which plays a buffering role. At the same time, the part of the first groove near the bottom forms a slope with the plane of the first groove. This shielding arrangement prevents the external wire harness from bending in the first groove and avoids damage to the external wire harness.
[0030] In one possible implementation, a positioning block 230 is also included. The number of positioning blocks 230 is two, which are respectively set diagonally above the two apex corners of the top of the first groove.
[0031] Specifically, such as Figure 2 As shown, in order for the pressure block 200 to be used in conjunction with the raised end cap structure, the raised end cap structure has two protrusions. The specific position of the pressure block 200 needs to be aligned with the two protrusions on the raised end cap structure. Therefore, a positioning block 230 is provided. The positioning block 230 is a cylinder, and two positioning blocks 230 are provided. They are respectively set on the top of the two apex corners of the first groove, corresponding to the protrusions of the raised end cap structure.
[0032] In one possible implementation, two second through holes are provided on the pressure block 200, and the pressure block 200 is fixed to the external raised end cap structure by external bolts passing through the second through holes.
[0033] Specifically, such as Figure 2 As shown, in order to fix the pressure block 200 to the raised end cap structure, two second through holes are opened on the pressure block 200, and the pressure block 200 is fixed to the external raised end cap structure by external bolts passing through the second through holes.
[0034] In one possible implementation, the distance between the two latches 110 is the same as the distance between the two slots 220. This arrangement ensures that the latches 110 are properly engaged with the slots 220, preventing misalignment and unusable situations.
[0035] In one possible implementation, one side of the protrusion 210 is a cylindrical structure, and the cross-section of the protrusion 210 gradually tapers as it extends toward one side of the pressure block 200. Multiple protrusions 210 are provided. These multiple protrusions 210 are arranged along the vertical direction of the pressure block 200.
[0036] Specifically, such as Figure 2 As shown, the specific shape of the bump 210 is a cylindrical structure on one side, and the cross-section of the bump 210 gradually decreases as it extends toward the pressure block 200. This arrangement allows the bump 210 to present an arched shape with a flat top, which can further increase the pulling force of the external wire harness.
[0037] In one possible implementation, a relief groove 240 is provided on one side of the wire clamping block 200, the position of the relief groove 240 corresponding to the position of the second through hole, and two relief grooves 240 are provided. This arrangement facilitates the operator in tightening screws.
[0038] When using this application, the wire clamp 100 is first snapped onto the wire clamp block 200 by the buckle 110 and the slot 220. The external wire harness is fixed in the space formed by the arc-shaped through hole and the U-shaped groove and in the first groove. The pull force of the external wire harness is increased by the protrusion 220. Then, the positioning block 230 is aligned with the raised end cap structure, and the whole is fixed on the raised end cap structure by the bolt passing through the second through hole.
[0039] This application employs a wire clamp, a wire clamp block, and a protrusion. The wire clamp connects to the wire clamp block, and the two components work together to secure the external wire harness. The wire clamp is a trapezoidal plate structure with an arc-shaped through hole extending through the top of the clamp. The external wire harness passes through this through hole, and this design also allows the two ends of the top of the wire clamp to form a latch. The wire clamp block is a rectangular plate structure with a U-shaped groove open at both ends on one side. The U-shaped groove is designed to allow for connection with the through-hole. The holes mate to form a pressing space to accommodate the external wire harness. Slots are provided at both ends of the U-shaped groove, which cooperate with the buckles. This design secures the external wire harness, suitable for fixing the external wire harness between the wire clamp and the wire clamp block. A protrusion is provided on the wire clamp block and located within the U-shaped groove. The protrusion is designed to increase the pull-out force of the wire harness while simplifying installation. This solves the problem that existing wire clamps cannot achieve the required pull-out force, while also simplifying the overall structure and making installation easier.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
